Connecting Generator to RV Instead of Shore Power

Updated 05/11/2021 | Published 05/08/2021

Question:

Our new fifth wheel comes generator ready for an Onan genset. Could this be connected to the fifth wheel’s auto transfer switch. I understand I can plug our shore cable into the 50 amp outlet in the parallel box. I know it won’t be compatible with the installed prewired Onan controls. It’s a 2021 Crossroads CE3891MK. Thanks

Item # 333-H08051 can be used in place of an alternate gen-set. You will need to ensure the two share the same connector. The Onan arrangement is intended to be a permanent install whereas the # 333-H08051 is designed to be portable. However, if you choose to make this a permanent mount there is no reason you cannot. Otherwise I would simply plug in the portable generator to the shore power connection when you need generator power while boondocking.
